with decent engine management you should last the test of time .But you need to stay on top of the maintanance ....2k oil changes with synthetic oil a turbo timer and keep those coolent temps under control and yoyu should not have to many day to day problems. DiabloAutosports.com sells a super map controller for under 200 bucks it can control 450 cc injectors and 0 boost up 14 psi .So other than putting your timing in check and a good clutch your straight!

 

i also have a mostly stock motor and some gas
